Where to buy POLIS
All-in cost is the trading fee on a $1,000 market buy plus the cheapest fee that exchange charges to withdraw POLIS. It is the number the exchange’s own “how to buy” page never shows you, and it reorders the table more often than not. The coins column is how many assets each exchange lists in total, from our own sync — not the figure CoinMarketCap prints.

Buying POLIS step by step
- Pick a venue from the table. For a coin this size the choice is usually short — 6 exchanges list POLIS at all, and the table already shows what you will pay to leave as well as to buy.
- Fund the account. 6 of those exchanges take fiat, 4 of them by card. Card is fastest and dearest; a bank transfer costs a fraction of it. Depositing a stablecoin you already hold is free on almost every exchange here.
- Place the order. A market order pays the taker fee in the table; a limit order that rests on the book pays the lower maker fee. On a thinly traded coin the spread costs more than either, so a limit order is worth the wait.
- Decide whether to move it. Leaving POLIS on the exchange is free but custodial. Moving it to a wallet that supports it costs one withdrawal fee, from $1.50 — send a small test amount first, and match the network on both sides.
How to buy POLIS — FAQ
Where can I buy Star Atlas DAO (POLIS)?
On 6 exchanges we track: MEXC, Bitget, CoinEx, Kraken, HitBTC and 1 more. The table above has each one with its trading fee, the payment methods it takes and what it charges to withdraw POLIS.
What is the cheapest way to buy POLIS?
MEXC, at $2.00 to buy $1,000 of POLIS and withdraw it — $0.50 in trading fee plus $1.50 to move it out over Solana. If you are leaving the coin on the exchange, only the first half applies and a different venue may win. Paying by card adds the card processor's charge on top of both, typically 1.8–4%.
Can I buy POLIS with a credit card?
Indirectly, yes. 4 of the exchanges listing POLIS accept a card (MEXC, Bitget, Kraken, Bitrue), but the card almost always buys a major asset — USDT, USDC, BTC — which you then swap for POLIS on the same exchange. That means two fees: the card charge, then the trading fee in the table.
Do I have to pay a fee to withdraw POLIS?
Yes, and it is worth checking before you choose where to buy. It is a flat amount of POLIS, set by each exchange per network, so it does not scale with the size of your purchase — the cheapest in the table is $1.50 on MEXC. Our full POLIS withdrawal fee table compares every exchange and every network.
Is it safe to leave POLIS on the exchange?
It is a custody choice, not a safety switch. While the coin sits there the exchange holds the keys: convenient, recoverable if you lose your password, and dependent on the exchange staying solvent and keeping withdrawals open. Moving it to a wallet you control removes that dependency and costs one withdrawal fee — from $1.50 for POLIS. For a trading balance, staying put is reasonable; for a long hold, most people move.
Exchange coverage for POLIS comes from each exchange’s own deposit and withdrawal endpoints (last sync 2026-08-29 00:53 UTC); trading fees are the published base tier, no volume discount applied (verified 2026-08-28).
